m Refiled for abandoned application Serial No. 243,058, December 28,1927. This application December 7, 1936, SerialNo. 114,658 r V 5 Claims.(01. 16-141) The center hub has ablock. l8 fixed therein,

, My invention isa ratchet hinge for doors, having the ratchetscompletely enclosed in the hubs ofthe-hinge. This is a substituteapplication of my abandoned application, Serial -No. 243,058, filedDecember 28, 1927, allowed December 13, 1929 and forfeited for failuretopay the final fee.

An object of my invention is the construction of a ratchet hinge, withthe ratchets entirely enclosed in the hubs of thehinge and with a pintleextending through said ratchets, the pintle holding the ratchets inalignmentand forming means to remove one of the sets of ratchets when itis desired to assemble and disassemble the hinge, such as for taking adoor ofi the hinges.

Another object of my invention is the construction of an enclosedratchet hinge with what may be termed a fixed ratchet connected to oneof the center hubs of a hinge leai, and having opposite ratchetsengaging in keyways in the adjacent hubs of the other hinge leaf. Theselatter ratchets are slidable and press against the fixed ratchet bymeans of springs which engage washers, such washers being caught in thegrooves in the hubs having the slidable ratchets. A pintle extendsthrough the central hub and the hubs adjacent thereto, and preferablyhas its upper and lower ends fitting in sockets in nuts secured to theupper and lower hubs of a hinge leaf.

My invention will be more readily understood 7 from the followingdescription and drawing, in which:

Fig. 1 is a plan View of a hinge as if taken in. the direction of thearrow I of Fig. 2.

Fig. 2 is an elevation of a hinge as if taken in the direction of thearrow 2 of Fig. 1.

Fig. 3 may be considered a vertical section substantially on the line3-3 of Fig. 1 in the direction of the arrows, through the center of thehubs, with certain of the interior part shown in elevation.

Fig. 4 is a horizontal section taken on the line cylindrical. The upperand lower hubs have bushings l5- fitting therein, such bushings eachhaving a pair of opposite grooves It. The bushings have an internallythreaded section I! at the top and at the bottom, respectively, of thehubs l4.

such block having ratchet teeth [9 at both ends, that is, at the top andbottom, and this block has a bore through thecenter to accommodate thepintle 2B, which pintle has a central enlarged section 2| withreducedends 22 and shoulders 23 between such portions.

In each of the bushings of the hubs [4 there is a slidable ratchet 24having teeth 25 and opposite splines 26, these splines fittingin thegroove it of the bushings |5.. Bearing against each of the ratchets 2-lthere is a coiled spring 2'l whi ch bears against a washer 28,suchwasher having opposite tongues 29 fittingin the grooves IS. Theratchets 24 and the washers 28 have a bore to slide on the reduced part22 of the pintle.

There are two slidable ratchets, one in each of the hubs l4 and engagingthe teeth on the top and bottom of the central ratchet block [8. Thepintle and assembly are held in position by means of lower and uppernuts 30, such nuts having a reduced threaded section 3| engaging in thethreads l7 and. having sockets 32 to accommodate the upper and lowerends of the pintle 20. These nuts may have a screw-driver kerf 33, ifdesired.

The assembly and disassembly of the hinge is believed apparent; however,it may be stated that it is desirable to solder the ends of the springs21 to the ratchets 24 and to the washers 28, so that these may be liftedoii the reduced end of the pintles as a unit. However, presuming thehinges are to be disassembled, the lower nut 39 may be removed and, withthis nut, the lower slidable ratchet, the lower slidable washer andspring will drop downwardly by gravity; and if desired, the pintle maybe then removed. If the upper nut is first removed, then the upper endof the pintle may be grasped by the fingers and pulled upwardly, liftingthe upper ratchet, spring and washer, such ratchet then resting on theshoulder 23.

It will be seen by my construction that I secure a double ratchet actionon account of the central ratchet block and the two slidable ratchets inthe upper and lower hubs. In addition, the pressure of these ratchetstogether may to a certain extent be regulated by the degree to which thenuts are threaded into the upper and lower hubs.

It will be apparent by the above description that the ratchet mechanismis entirely enclosed in the hubs of a hinge and thereby is not exposedto dirt or dust nor does it give an unsightly ap-. pearance. In fact,the ratchet hinge made in accordance with my design cannot bedistinguished from the ordinary type of hinge, except as to the action.

Various changes may be made in the principles of my invention withoutdeparting from the spirit thereof, as set forth in the description,drawing and claims.

I claim:

1. A hinge comprising in combination a first leaf having a first hubwith a ratchet fixed therein, a second leaf having a second hubadjacent" thereto with a ratchet slidable but non-rotatably mountedtherein, a spring bearing on the slidable ratchet, a washer bearing onthe' spring, a

pintle extending through said ratchets, spring'and Washer, a nutthreadedly secured to a hub of one of the leaves, said nut having asocket, the end of the said pintle fitting in said socket.

2. A hinge comprising in combination a first leaf having a hub with afixed ratchet therein, a

second leaf having a hub with a bushing therein, said bushing having agroove, a slidable ratchet mounted in said bushing and having a splineengaging the groove, a pintle extending through said ratchets, a nutthreadedly secured to a hub of one of the leaves and-having a socket inwhich an end of the pintle fits, and means operated bythe nut to exert apressure on the slidable ratchet.

3. A hinge comprising in combination a hinge leaf having a hub with afixed ratchet mounted therein, a second leaf having a pair of hubs onopposite sides of the first 'hub and having slidable ratchets therein,said latter ratchets being non-rotatable as regards saidsecond hubs, apintle extending through the ratchets, nuts secured to the top andbottom hubs of the hinge, each nut having means to engage and centersaid pintle, and means operated by at least one of the nuts to exert apressure on at least one of the slidable ratchets.

4. A hinge comprising in combination a first leaf having a hubwith'a'fixed ratchetimounted therein, a second leaf having a second hubwith a ratchet slidably but non-rotatably mounted therein, a pintleextending through said ratchets and having a reduced end extendingthrough the slidable ratchet with a shoulder adjacent thereto, anutsecured to azhub of one of the leaves and having means to engage andcenter said pintle, and means'operated by the nut to exert a pressure onthe slidable ratchet, said slidable ratchet beingremovable on theremoval of the pintle by engaging the said shoulder.

5. A. hinge comprising in combination a first leaf having a first hub,.a second leaf having a second hub, a fixed'ratchet in the first-hub,a-ratchet slidably but non-rotatably mounted in the second hub,- aspring bearingon the second ratchet, a washer bearing on the spring, thewasher being non-rotatable but slidable in relation to the second hub,the washerbeing secured to the spring and the spring to the slidableratchet, a pintle extending through said ratchets, and means engaging ahubof one of the leaves exerting pressure onthe washer, the washer,spring and slidable ratchet being removable and insertable as a unit.
